CP2112 Adaptor

[Rickkap]

Hi

This might be a noob question but I've just received a CP2112 and I would like to reset a MacBook battery, I've downloaded the demo software, but i'm not sure what else I need and how to wire the CP2112 to the battery. If anyone can help I would really appreciate it.

I have followed what is said on the you tube video but I cannot connect to the battery. The battery is from a MacBook Air and has 3 x live pins, 3 x gnd pins, SMC_SCL and SMC_SDA pins and finally SYS_DETECT pin. I've opened the casing and the chip is BQ20Z451.

Will the CP2112 work with this battery and if so which pins do I need to connect the D & C to? I've tried all types of combinations but it doesn't read the battery info.

Thanks

I have followed what is shown on the you tube video but I can't read the battery.

The battery is from a MacBook Air and has 9 pins, they are as follows

First 3 pins are -ve
next pin is SMC_SCL
next pin is SMC_SDA
next pin is SYS_DETECT
and the last 3 are GND

I have connected G from the 2112 to GND and I've tried to connect SCL & SDA to D & C but I can't make it read the battery

What am I doing wrong.

Thanks

D - SMC_SDA
C - SMC_SCL
G - GND

Thank you

That worked.

Another question, what does this mean?

Device Type: 0451
Firmware Version: 5.11
Hardware Version: A6
Manufacturer Status:
FET1|ST3|ST0|
Chemistry ID: 1210
---------------------------
Unable to unseal
No Full access

And if I buy the full version will I be able to continue past this?

No.
Current version of BE2Works can't remove password for BQ20Z451 with firmware higher then 5.00

[Rickkap]

Will it be able to remove password in the future?

[admin]

Yes.
